  • 在分析ASP.NET页面的时候，在System.Web.UI.HtmlControls.HtmlControl类中，样式信息被填充到CssStyleCollection类型的Style属性。这个属性本质上是一个字典，它把控件的样式暴露为每个样式属性键的按字符串索引的值集合。例如，你可以使用下面的代码设置和检索HtmlInputText服务器控件的width样式属性：

    ＜script language="VB" runat="server" ＞Sub Page_Load(Sender As Object, E As EventArgs)MyText.Style("width") = "90px"Response.Write(MyText.Style("width"))End Sub＜/script＞＜input type="text" id="MyText" runat="server"/＞

    下面的例子显示了如何编程使用Style集合属性来控制HTML服务器控件的样式：

    ＜script language="VB" runat="server"＞Sub Page_Load(Src As Object, E As EventArgs)Message.InnerHtml &= "＜h5＞Accessing Styles...＜/h5＞"Message.InnerHtml &= "The color of the span is: " & MySpan.Style("color") & "＜br＞"Message.InnerHtml &= "The width of the textbox is: " & MyText.Style("width") & "＜p＞"Message.InnerHtml &= "MySelect's style collection is: ＜br＞＜br＞"Dim Keys As IEnumeratorKeys = MySelect.Style.Keys.GetEnumerator()Do While (Keys.MoveNext())Dim Key As StringKey = CStr(Keys.Current)Message.InnerHtml &= "＜li＞  "Message.InnerHtml &= Key & "=" & MySelect.Style(Key) & "＜br＞"LoopEnd SubSub Submit_Click(Src As Object, E As EventArgs)Message.InnerHtml &= "＜h5＞Modifying Styles...＜/h5＞"MySpan.Style("color") = ColorSelect.ValueMyText.Style("width") = "600"Message.InnerHtml &= "The color of the span is: " & MySpan.Style("color") & "＜br＞"Message.InnerHtml &= "The width of the textbox is: " & MyText.Style("width")End Sub＜/script＞
